Yep, my phone picks up all the signal, same with my friend's notebook. I wouldn't blame my modem, I'm pretty sure it's my Y400 the one that has the problem. It's weird, sometimes I get the full signal but drops to 1 or 2 after a few seconds, I really don't know what to do.

Hi guys, I own a Y400 and modded the BIOS like 1-2 months ago to change the crappy wireless card (intel 2230) to an Intel 6235, since then everything related to wifi has been working like a charm, but suddendly 2 days ago, when I was getting full signal from my modem, I started to get only 3-4 bars and even sometimes 2 bars though I'm only a few feets away from it. Sometimes I'm able to get full signal but it doesn't last too long until it gets dropped to 4 bars. Also when it was working fine the wifi was able to discover 15+ wifi networks on my apartment, now it can only find 4 if I'm lucky. The bad thing is that I'm not able to download as fast as it used to be.

I've tried anything I've been able to do, from flashing back the 2.02 modded BIOS, to switching the position of the notebook's antennas, but nothing works...

Do you guys have experienced something like this with your wifi cards?

If I flashed from 2.02 to 2.04, can I flash the 2.02 version back? And if so, how can I do that?

The part list in the maintaince manual of the Y500/Y400 contains the "WLAN, 3*3 Intel 6300N MOW M PCIE NB HMC (LI) 20002323 **".

Is it possible to use this card without moddes bios? Do the Y500 have 3 antennas to connect it with that card otherwise it makes no sense to use it. The card has no blutooth support. I guess that means if using it the y500 have no bluetooth anymore. Please correct me if I am wrong.

Just installed it, as you say it does have some lag spikes, but I waas able to solve it in some way by just switching from 802.11 a/b/g to 802.11 b/g on the Advanced tab of the adapter (device manager), I'm not sure if it's a windows 8 problem or it's something with the adapter itself as I've been reading that many other people have same issues with lag spikes and disconnections.

Mine has been fine, did you buy it off ebay? 90% of the time the ones on ebay are es cards (engineering samples) which is fine most of the time some are junk, I had an es 6300 that would only get 1mbps on the 5GHz band.

Update to 2.04 for all v2.02 and v2.03 users. Should work flawlessly, I still have no machine to test it myself but I see no reason why this would cause issues.

Let me know if all is fine.

What does this new modded BIOS version fix?

What about the range increase? I'm completely sure it's better than the crappy Intel it comes with, though I already bought the Intel 6235 I'd really like to know how much signal strenght can the Killer get and other simple things.

Got it in today, will post review with speed test.net and ftp to nas comparisons vs desktop on ethernet

Hi Kamnnoriel, I haven't modded my BIOS yet. Truthfully still working towards unlocking the features of my account here on the TechInferno forums. As soon as I do, I will run a series of tests and capture the data for everyone. First with the 2200 adapter and again with the 6235 adapter. I'll specifically compare the 2.4 GHz range. I know for myself personally, the move to 5 GHz will make all the difference in the world.

Hope it'll be much of an improvement, and now you have the 5 posts you need, so go for it! Good luck

I Have a probleme with my ideapad y500

i dónt have any intel hd graphic and intel start thechnolgies what i muss to do ?

The Y500 doesn't have the Intel HD gpu enabled, I've read that it is disabled from the processor itself, so you can't enable it no matterr what you do, it's a hardware problem.

Check out my post, I actually just bought the GN35 and it should be here sometime in July. I've talked to a few different reps and whenever they do have them in stock they will be the 750m version.

I'll be waiting your report mate! Thanks for taking the risk of buying it, hope it is the 750m so all the Y400 owners can upgrade to a dual graphics 14" beast

Then I shouldn't buy the UB card? I know their support isn't good and not aware of what their selling sometimes, but I'd really like to hear from somebody if the GN35 is actually the 750m or not.

Thanks for the great info guys. I too bought a 6235 as a replacement. I have had nothing but grief with the stock card and operating over 2.4 GHz. The bluetooth can be sketchy some times as well. I have to mod my BIOS first but I'll report back on my findings. I imagine the switch to 5 GHz will make all the difference. My X201t doesn't have any wireless issues and is on 5 GHz.

Do you have better range with the 6235? or it's just a 5GHz capable card? I'm also interested in buying it in case that the Killer N-1202 doesn't work for me, any information you can give me will be much appreciated mate!

I spoke to a rep not 2 days ago and was told that they are not compatible. They have the Y400 750UB card but they are not going to be available for shipping until July 24th if you ordered 2 days ago.

TLDR: No, they don't work together. You need to call in and order the 400 version.

I didn't understand the shipping availability very well, you mean that the GN35 that's available for purchase on Lenovo 's site is actually the new GT 750m? I thought that the GN36 was the GT 750m, or they haven't updated the product's page yet....

okie dokie thanks again for assisting me my friend

EDIT: okay now i can't boot into my USB these are the files' placements and i formatted the USB with the tool and have USB boot enabled in the BIOS so please tell me what is wrong

Sorry I made a mistake, you don't have to copy the 98 files into the pendrive, just the requested ones as the main guide. The 98 files folder is only required for formatting the USB for DOS. Do as octiceps says .

thank you, will report back after i've done this. BTW whats the worst that could happen if i mod my bios?

If you don't mess with things you're not sure about probably you'll brick your notebook, else than that nothing bad could happen , and if by some reason you have to send it back to Lenovo try to flash back your BIOS backup (I'm not sure if you can do this)

so i have to copy the folder win98 to the root of the empty formatted drive?

Yup, after you formatted with the DOS formatting tool of course.

Try restarting the system. There's a bug with Windows 8 where Bluetooth disappears when you put the computer to sleep, hibernate, or use hybrid shutdown. The only way to get it back is to restart the system or perform a full shutdown and boot. It has nothing to do with the BIOS mod.

what do you mean by doing a full shutdown? you mean removing the battery and disconnecting it from AC? because if it's justa normal reboot then it doesn't work...

kudos my friend. Don't worry i also suck at english haha and in Prepare an USB stick which can boot DOS. If you don't know how to do this, follow this short guide:" should the USB pen drive be empty? What I mean here is AFTER the format with the utility and the whole win98 folder thing because AFTER this my USB is empty after the format

It's better to backup all the pendrive's content before formatting it with the DOS formatting tool, and of course, after you format the pendrive with that tool it'll be empty, so there you have to copy the 98 files and paste them inside de pendrive (after de DOS format is complete), then keep following the main guide and you'll be ready to format . hope this helps you

You're in Windows 7? You need to navigate to the folder where your fpt tool is, you're currently in the system32 folder... If you don't know how to use the cd command to do so, then just go to the folder where you saved the fpt, shift+right click and then "open command window here".

The USB drive will get formatted, if it had files on it before they will be erased afterwards.

Hey svl7 after I flashed the custom v 2.02 BIOS on the Y400 I'm not able to use Bluetooth....it doesn't detect it. Do you know how to re-enable it? Or the modded BIOS disables the Bluetooth feature completely? Perhaps I did something wrong while flashing

how can i backup my bios? i am stuck on this problem please help

BTW in "Prepare an USB stick which can boot DOS. If you don't know how to do this, follow this short guide:" should the USB pen drive be empty?

I know there's a betterr way to do this, but if you pay attention to the pic, the root folder where it is expecting to open the fpt.exe is system32, so what I did was simply copy all the fpt folder's content to system32, after that I opened the backup.bat and it worked . The BIOS's backup was created in the same folder (system32). I repeat, I know that's not the correct way to do it, but at least it worked for me . PS: sorry for my english.

My country has Belgacom BBOX2 most crappy routers ever. Limited to 802.11g and 100Mb/s I am never able to get my ASUS EAN66 running at 450Mb/s probably because of the 100Mb/s limit. I'm stuck with 54Mb/s

But if u want a supported card. A 6300 Ultimate-N will do from Intel.

If you buy the 6235 you get bluetooth. But this card was kinda unstable with every driver. Partially because of Windows fast boot. Having Bluetooth AMP turned on with this card resulted into BSODs with ntfs.sys. What doesn't make sense. But believe me I found the link after watching it for 3 months.

The 2230 has indeed a very high ping.

Not sure the 6300 will do a good job, some people have reported that you have to disable wireless LAN in the BIOS, restart, and then enable it again so it will be able to connect to a network.

I wouldn't waste you time and $ on the N-1202, get the AC-7260, it cheaper and is on the latest wireless tech. The N-1202 are descent but the price tag I'm not a fan of. (At least here in canada their pricey)

The N-1202 costs like 47.99 on Amazon and the AC-7260 is about the same price (eBay at least) but I'm not so sure if it'll work well since it's kinda "new" in the market (and it'll probably have driver related issues), what I want to know if it'll be better than the N-1202, I mostly game on this notebook so if the AC-7260 performs better than the N-1202 I'll probably upgrade to it .

Question... If I'm using a y400/500 with the 650m and bios v2.02, would I be able to upgrade to 2.03 or 2.04 (since I believe those include 750m BIOS, not 650m)?

I had a 6300 in asus g73j and all I did was buy the 3rd antenna and coil it up in a vacant spot that would disrupt anything, and I got consistent 270-450mbps

Just wanted to know if the Ultrabay graphics GN36 for the Y500 which seems to be the GT 750m will be compatible with the Y400 w/ GT 750m, or the GN35 for the Y400 is actually the updated 750m (I've read that the GN35 is still the GT 650m as some people say...). I want to make a GT 750m SLi in the Y400 and I don't see any reason why Lenovo wouldn't make the GT 750m for the Y400 since both GT 650m and GT 750m use the same core .
